RESOURCE ALLOCATION IN TARGET CELL AFTER HANDOVER

摘要

A system is proposed to provide handover in a mobile telecommunications environment, particularly applicable to 3GPP networks, in which a user device, such as a mobile telephone provides a buffer status report to the target base station during a handover procedure. The target base station uses this status report to allocate appropriate resources for uplink data to be transmitted from the user device to the target base station.

1. A communications device which communicates with a target communications node, the communications device comprising:
a memory storing instructions; and one or more processors configured to execute the instructions to: receive control data before the communications device synchronizes with the target communications node; transmit a handover complete message together with a buffer status report to the target communications node, wherein the buffer status report comprises information of an amount of buffered uplink data stored in an uplink data buffer; and transmit uplink data to the target communications node using a resource, for transmission of the uplink data, allocated by the target communications node based on the buffer status report.
